This question falls outside Liu Kai's area of knowledge.
He had only ever worked on land that grew tobacco, so he really didn't know much about grains.
Seeing him shake his head, Qin Luofei didn't keep him in suspense any longer.
"With today's technology, one acre of land can support three people a year by growing grain and vegetables."
"If soybeans are planted to synthesize artificial meat, one acre of land can only support two people."
“If we use the traditional method of planting pasture to raise livestock, one acre of land can only support 1.5 people.”
"Currently, there are 137,000 survivors in the Fenghai City shelter. If the number does not increase, even using the first method, it would require 46,000 mu of land to feed them."
"The shelter only occupies 435 acres!"
"Even with hydroponics technology, reducing the required area by 10 times is far from enough."
Liu Kai has never lacked food or clothing; this is the first time he has heard specific calculation data.
46,000 mu of arable land—what a despairing number.
Admittedly, the population decreased significantly after the cold wave.
The supplies buried under the thick ice layer are like a rich gold mine.
But mining is easier said than done, and even if it were possible, there would be a day when the resources would be depleted.
Furthermore, there are still a large number of survivors in Fenghai City who have not come to the shelter due to distance.
Digging all those things away would undoubtedly cut off these people's last hope of survival.
Thinking of this, he couldn't help but worry about Qin Luofei.
If I were in this position as director, I would be dealing with the daily needs of hundreds of thousands of people.
How can this be resolved?
How long can the reserve grain obtained from the grain bureau's warehouse last?
Unable to resist asking, "Does the higher-ups have any good solutions?"
"No."
What about other countries?
"Hehe, China is a vast country with abundant resources. If we can't handle it, most other countries can only watch helplessly."
"However, the Japanese government is already secretly encouraging people to eat human flesh."
Liu Kai was horrified: "Eating human flesh? Aren't you afraid of prions?"
"Prions are mainly in the brain, so it's not a big deal if you don't eat brains."
Upon hearing this, Liu Kai fell silent.
In this era, people only talked about survival, not ethics, and besides, the Japanese had never had any ethics.
Qin Luofei picked up her lunchbox and continued eating, but then remembered something and casually mentioned it.
"I've heard that several major powers are discussing the feasibility of building a super-large space station."
"A large space station? What's the point of building that?"
Qin Luofei shrugged: "It's also a backup plan in case the 'Earth Thawing Plan' fails."
"If we can't grow food on Earth, we can only grow it in space."
"With plenty of sunlight and no gravity, plants grow very quickly and very large."
Liu Kai was shocked by this bold idea, but then shook his head, thinking it was not very realistic.
Growing grain always requires transporting water and fertilizer.
When the grain ripens, it must be harvested and fed to people.
Even if China's spaceplane technology is mature, the cost of traveling between space and the ground is very low.
But it can't withstand such extravagant back-and-forth travel.
However, this idea provided Liu Kai with a completely new inspiration.
Even in the apocalypse, with current technology, there is not much of a shortage of energy.
What's lacking is land suitable for growing crops!
And Liu Kai happens to have just one perfect spot: storage space.
He roughly estimated that the floor area of the storage space was only a few hundred acres.
However, its shape is a standard cube, which is many times taller than ordinary hydroponics workshops.
so.
His several hundred acres of space are equivalent to a soilless cultivation factory of tens of thousands of acres!
This trip to Japan to absorb nuclear fuel for reinforcement will likely result in an even greater increase in storage space.
Inside the storage space.
It has no shortage of air and fertilizer, and can even open gaps to let in sunlight.
The most crucial point.
The flow of time within the control space is accelerated.
Five harvests a year, or even ten?
It sounds wonderful.
This is practically tailor-made for farming!
But inspiration is inspiration, and Liu Kai has no intention of revealing it now.
After all, humanity has not yet reached the critical point of running out of ammunition and food.
It simply planted a seed in my heart.
If all goes well, he will officially marry Qin Luofei in six months.
He had originally planned to reveal his spatial abilities to her at that time.
He didn't live to see that point in time in his previous life, so he doesn't know if the Earth has thawed.
If you don't have it yet, it's not too late to start your farming journey after you reveal your spatial abilities.
That might even help Qin Luofei achieve political success and rise to the rank of general.
He pictured her with the rank insignia of the Sui Xing military officer hanging on her collar, her face aloof, ascetic, and old-fashioned.
Liu Kai couldn't help but laugh out loud.
Rebirth: My Wife is a General
Qin Luofei was completely confused and asked curiously, "Why are you laughing so happily? Have you thought of something wonderful?"
"Oh no, it's just that the way you called me 'husband' just now was so domineering!"
"Don't mention this again! I didn't!"
Liu Kai was in a good mood and quickly finished his dinner, ignoring Qin Luofei's excuses.
"Let's go, honey, we're going to a meeting."
Qin Luofei also put down the empty bowl and wiped her mouth.
With a wave of his hand, he said, "Let's go! Wait, what did you just call me?"
"Hey Liu Kai, stop running! Explain yourself!"
...
The two of them ran out of the office one after the other, playfully chasing each other.
However, once they entered public areas, they reverted to their usual aloof and serious demeanor.
The meeting room is also located on the top floor of the central area.
